You also left out that besides company logos there were also real people's faces used that the fake Trump was brutally murdering. Clinton, Sanders and Pelosi I believe were some of those depicted. Seeing Trump stab, shoot and kill his political rivals played at this Trump event without any people seeing it and reporting it to anyone in charge apparently. Or maybe people did and their just lying about not knowing. Or scarier yet nobody there really had an issue with it.
I've seen reports that the video was being shown on a tiny screen in the corner of one room as part of an art installation. It's not like it was being shown a jumbotron to the assembled coventioneers.
That being said, I agree with you that once the creator put real people's faces on some of the victims it crossed a line. Trump shooting a CNN logo is kind of funny in an over the top way. Trump stabbing Obama or shooting McCain is a very different thing.
